Israel v. Palestine again and again and again

So let's go over this one more time.

A. Some Palestinians (Hamas) shoot some un-aimed missiles into Israel (if they're lucky) causing some damage and injuries and a death or two if they get lucky.

B. The Israelis bomb the fuck out of Palestine killing hundreds, mostly civilians.

C. In retaliation to the incredibly lopsided Israeli response to the first missiles, Hamas shoots some more missiles into Israel, occasionally hitting their own people by accident.

D. The Israelis bomb the Palestinians even harder and invade with tanks, destroying all buildings and everything else that might help the Palestinians without actually affecting Hamas.

E. Angry Palestinians blow themselves up to kill Israelis.

F. Israel blows up more of Gaza and takes more Palestinian land by cutting it off with a fence.

G. Go back to A.

And around and around and around we go.

Every time this has happened since I was a child I've thought Israel's response was WAY over the top, punishing the Palestinian people for the act of a group they do not necessarily support. But the more civilians Israel kills, the more people support the attacks. After the deaths of civilians and bystanders the Palestinian people march in the streets against Israel. This is especially senseless in the case of these rocket attacks as by the time Israel responds the trucks that fired those rockets are miles away so Israel is punishing the people that had the misfortune of living there. Does Israel expect shopkeepers and teachers to run out and attempt to stop the rocket launch?!? Do they doubt the rapid response from an AK-47 that would result? Israel treats all Palestinians as combatants, is this fair? It makes no sense to me yet something like this happens every time. And in retaliation this time Israel directly targeted the Gaza police force, including a graduation ceremony. Even if some of these police are Hamas fighters, what about all the ones that aren't? Doesn't Israel need a robust police force in their neighbor? Kill 'em all seems to be the Israeli motto. It would not surprise me if Israel becomes the second country to use a nuclear bomb.
